Figure S1. Open-aperture Z-scan traces of 1 in dichloromethane (+) at various

wavelengths and with incident powers (from top to bottom): at 1280 nm with incident

powers of 0.10, 0.30, 0.46, and 0.61 mW (A), at 1360 nm with incident powers of 0.11,

0.31, 0.37, and 0.65 mW (B), at 1590 nm with incident powers of 0.15, 0.40, 0.60, and

0.75 mW (C), and at 1520 nm with incident powers of 0.05, 0.14, 0.24, and, 0.37 mW

(D). The baselines are shifted by one division (0.02) for readability. The solid lines are

curve fits based on Eqs. 3 and 4 in the text (Experimental section). The concentrations

were 4.8 mM for all. Rayleigh ranges were 12.5, 13.2, 13.6, and 14.0 mm for A, B, C,

and D, respectively.

Figure S2. Plots of two-photon absorbance q0 of 1 in dichloromethane against the

incident power at various wavelengths: 1280 nm (A), 1360 nm (B), 1590 nm (C), and

1520 nm (D). The q0 values were obtained by the curve fits in Fig. S1. The lines are


linear fits to the data points.
